Resources and Additional Insights

Reference Designs

  • Signal Processing Subsystem and Current Input Based Self Power for Breaker Applications (ACB/MCCB)
    TIDA-00498: THe TIDA-00498 reference design features signal processing front-end and self-power block for electronic trip unit (ETU) used in circuit breakers. A FRAM based micro-controller is used for processing current inputs from signal conditioning amplifiers for 3-phase, neutral and ground current. Two gains are used to extend the range for phase current measurement. This reference design can also self-power using rectified current input. TIDA-00498 is desiged for fast and repeatable tripping (within 30mS) for wide current and temperature range.
  • TIDA-00772 18-V/400-W 98% Efficient Compact Brushless DC Motor Drive w/Stall Current Limit Reference Design | TI.com
    TIDA-00772: The TIDA-00772 is a 18 A RMS drive for a three phase brushless DC (BLDC) motor in power tools operating from a 5-cell Li-ion battery with a voltage up to 21 V. This design is a 45 x 50 mm compact drive implementing sensor-based trapezoidal control. The design uses a discrete, compact MOSFET-based three-phase inverter delivering 18 A RMS continuous (60 A peak for 1 second) winding current, without any external cooling or heat sink. The slew rate control and charge pump of the gate drive ensures maximum inverter efficiency (>98% at 18V DC) and optimum EMI performance. The cycle-by-cycle overcurrent protection feature protects the power stage from large stall currents and the board can work up to 55°C ambient. The small form factor enables flexible mounting of board, high efficiency brings more battery duration and the 60 A peak current capability provides high momentary peak torque in power tools.

  • 230-V, 250-W, High Efficiency BLDC Motor Drive w/DC Bus Voltage Ripple Compensation Reference Design
    TIDA-00472: The TIDA-00472 is a discrete IGBT-based three-phase inverter for driving brushless DC (BLDC) motors rated up to 250 W, for example, used in cooker hoods, using a sensor-less, trapezoidal control method. The design provides software implementation for DC bus voltage ripple compensation resulting in 30% reduction in the DC bus capacitor requirement and reduced overall BOM cost. The cycle-by-cycle overcurrent protection feature protects the power stage from large current spikes and the board can work up to 65°C ambient. This design has also been tested to pass EN55014 standards for conducted emissions, Surge and EFT.

  • TIDA-00661 High Resolution, Fast Startup Analog Front End for Air Circuit Breaker Reference Design | TI.com
    TIDA-00661: The TIDA-00661 reference design features signal processing front-end subsystem for electronic trip units (ETU) used in air circuit breakers (ACB) or molded case circuit breakers (MCCB). This subsystem consists of Delta-Sigma ADC with 24-Bit resolution and fast startup (< 3ms), ±2.5V regulator, FRAM-based microcontroller (MCU) for interfacing to ADC and processing the inputs. The subsystem is designed to start-up, compute full-cycle RMS current, make decisions, and provide trip signal to the solenoid within 30 ms.
  • TIDA-00771 10.8V/250W, 97% Efficient,Compact Brushless DC Motor Drive w/Stall Current Limit Reference Design | TI.com
    TIDA-00771: The TIDA-00771 is a 20 A RMS drive for a three phase brushless DC (BLDC) motor in power tools operating from a 3-cell Li-ion battery with a voltage range of 5 V to 12.6 V. This design is a 45 x 50 mm compact drive implementing sensor-based trapezoidal control. The design uses a discrete, compact MOSFET-based three-phase inverter delivering 20 A RMS continuous (70 A peak for 1 second) winding current, without any external cooling or heat sink. The slew rate control and charge pump of the gate drive ensures maximum inverter efficiency (>97% at 10.8V DC) from 5 V to 12.6 V and optimum EMI performance. The cycle-by-cycle overcurrent protection feature protects the power stage from large stall currents and the board can work up to 55°C ambient. The small form factor enables placement of board close to the battery pack, high efficiency brings more battery duration and the 70 A peak current capability provides high momentary peak torque in power tools.
